WebThe melting point of a substance is the temperature at which it changes state from solid to liquid at atmospheric pressure; at the melting point, the solid and liquid phases exist in equilibrium. A substance's melting point depends on pressure and is usually specified at standard pressure in reference materials. WebThe melting point and freezing point are the same temperature for any particular substance: 32°F (0°C) for water. This temperature is referred to as the melting point when temperatures rise above 32°F (0°C), causing ice to melt and change state from a solid to a liquid (water), as happened with the cup of crushed ice at room temperature.
